Dec 17, 1985 - The grasshopper central nervous system is composed of a brain and a chain of segmental ganglia. Each hemiganglion contains about 1000 neurons, most of which can be individually identified by their unique morphology and synaptic connectivity. Shortly

Dec 17, 1985 - Studies of the role of cell lineage in development began in the latter part of the 19th century, fell into decline in the early part of the 20th, and were revived about 20 years ago. This recent revival was accompanied by the introduction of new and
